Novel underwater tunnel wastewater pumping station

Abstract

The invention discloses a novel underwater tunnel wastewater pumping station, and relates to the technical field of underwater tunnel water supply and drainage. A dredging type collecting tank is divided into an upper bin and a lower bin by a middle partition wall, and the upper bin and the lower bin are connected by virtue of a first gate and a third gate; a zigzag type anti-scouring water inletgallery is arranged in a water inlet adjustable water distribution room, a desilting channel is formed in one side of the zigzag type anti-scouring water inlet gallery, a water distribution tank is connected to one side of the desilting channel by virtue of a second gate, stainless steel grillings, garbage pools and drainage ditches are arranged on both sides of the water distribution tank in sequence, the both sides of the water distribution tank are respectively connected with a left tunnel and a right tunnel, water collection pits are formed in the drainage ditches, and a communicating holeis formed in the water distribution tank. According to the novel underwater tunnel wastewater pumping station, the main problems of an existing underwater tunnel wastewater pumping station can be solved, a strong guarantee is provided for the stabilization of an underwater tunnel drainage system, and when an emergency water bin needs to be extended, the extensible end wall can be broken so as toextend to both ends, so that the extension of the emergency water bin is realized.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage of underwater tunnels, in particular to a novel underwater tunnel wastewater pumping station. Background technique [0002] With the development of society and the continuous improvement of people's transportation needs, more and more underwater tunnels have been built. Because most of the underwater tunnels are designed with V-shaped slopes and have the lowest point, the tunnel wastewater cannot be discharged by itself, so a drainage system needs to be installed. The drainage system is the key to the safe and stable operation of the entire tunnel. Once it fails, it may lead to catastrophic consequences of flooding the tunnel. The wastewater pump room is an important part of the drainage system. Whether it is fully functional and easy to use directly determines the drainage Whether the system is safe and reliable. [0003] At present, there are many problems in the domestic und...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many problems in the domestic underwater tunnel wastewater pumping station, the main problems are as follows: 1. It is impossible or difficult to realize the dredging of the dry pool, and the dredging is inconvenient; The control equipment is installed in the water pump room, and the humid environment of the pump room seriously corrodes the electric control equipment; 4. The large amount of sand in the influent affects the life of the drainage pump

5 The emergency reserve and discharge operation of the emergency water tank is complicated, and there is no expansion capacity
